Question: I am having difficulties having a set of Magna 3 pumps connect for alternating control. Getting a fault code (77) when I pair them through their Bluetooth connection. Never had this happen before, any suggestions?

Answer: If you are familiar with setting up lead-lag control and your having the communication fault code “77”, it is most likely one is an “A” series and the other a newer “D” series. (This can be verified by checking the name plate located on the right side of the pump head as you are facing it.) Both Magna’s need to be the same series to talk to each other.

The fix is to go from home over to the settings tab, then scroll down to bus communication, then multi-pump profile selection. Select the A,B,C compatibility option and then go through the normal assisted multi-pump set up.
